DRIVE TRAIN ASSEMBLY FOR UNMANNED AIRCRAFT

摘要

PROBLEM TO BE SOLVED: To provide the optimum design for maximizing the allowable mistake alignment by connecting the torque to a driving shaft through an internal spline connection by the complementary engagement of spline teeth between the internal spline connection and an external crown spline connection. SOLUTION: An engine connection sub-assembly 63 includes a fastening fitting 64, a taper adapter, that is, a band pan 65, a ball bearing 66, an external crown spline connection 61, an internal spline connection 68 and a pin collar connector 69. The fastening fitting 64 is used for firmly fixing the engine connection sub-assembly 63 and a taper output shaft 54S of an engine. The fastening fitting 64 is mechanically mutually connected to the band pan 65. A center of a sprag clutch 62 is placed on an intermediate between the external crown spline connection 67 and the band pan 65 by means of the ball bearing 66. The external crown spline connection 67 is mechanically mutually connected to the internal spline connection 68.
